It is a great old-school fps game. It has a superb sigleplayer, and the multiplayer looks great, but not enough people play it. It is a forgotten gem.

Day of Defeat is a classic, realistic WWII shooter. It feels essentially like a WWII varient of Counter-Strike. It also has some amazing community maps.

Verdun is the most realistic WWI shooter out there. The music on the loading screen is superb and the squad based tacticality is extremely immersive.

It is an extremely competitive first- person shooter. It is easy to learn, but darn near impossible to master. It is also a ball to play with friends.
